perf tools: Test -fstack-protector-all compiler option for inclusion in CFLAGS

Some architectures (e.g. Alpha) do not support the
-fstack-protector-all compiler option and the use of the option
with -Werror causes the compiler to abort and the build fails.

Test that the compiler supports -fstack-protector-all before
inclusion in CFLAGS.
